Abstract (en)

[origin: WO0143827A1] A respirator system (10; 100) for a worker in an environment with hazardous airborne contaminants comprises a respirator (12, 112), a helmet (14, 114), a camera (40, 140), and a gas sample analyser (16, 116) capable of analysing samples of gas from within the respirator and in the immediate area near the user. An RF emitter (20, 120) sends a signal to a remote receiver (24, 124). The emitted signal is a real time view through the camera (40, 140) and overlaid on that is a graphical representation of the protection factor being achieved by the respirator. The system (100) may also have a data storage device (162, 170) to store data such as how protection factor varies with time and may have a position sensor (160). The provision of the position sensor (160) allows a map of contamination levels with position to be built up as a user moves around a site.
